Problems solved by technology

At present, the power distribution form of high-power DC charging piles with multiple guns is mainly in the form of high-voltage DC contactors. The high-voltage DC contactors are installed separately inside the charging pile cabinet, and the production, installation and wiring are more complicated.
At the same time, in terms of after-sales maintenance, it is not easy to replace the DC contactor, which brings inconvenience to production and after-sales

Abstract

The invention relates to a direct-current charging pile power distribution one-input four-output switch module device which comprises a switch module control panel, eight high-voltage direct-current contactors, a state indicator lamp, an address selection dial switch and the like. The switch module control panel is electrically connected with the address selection dial switch, and the switch module control panel is electrically connected with the high-voltage direct-current contactor through a tinned copper bar in a lap joint mode; the switch module control panel is provided with a CAN communication interface, and communicates with the DC charging pile main controller to realize on-off control of the eight high-voltage DC contactors. The high-voltage direct-current contactor is provided with a feedback contact, and the switch module control panel has a feedback contact detection function. According to the invention, the charging module can be switched to any charging gun, so that dynamic distribution of power is realized. According to the invention, the problem of inconvenient wiring and installation caused by too many high-voltage direct-current contactors can be well solved, andafter-sales maintenance is facilitated.

Description

technical field [0001] The invention belongs to the technical field of DC charging piles, and in particular relates to a DC charging pile power distribution one-input and four-outlet switching module device and a control method, which are mainly applied to one machine and four guns DC charging piles. Background technique [0002] With the development of battery technology, the power required for electric vehicle charging continues to increase, and high-power DC charging piles with one machine and multiple guns are currently being used more and more. Among them, the dynamic allocation of power is mainly involved. At present, the power distribution form of high-power DC charging piles with multiple guns is mainly in the form of high-voltage DC contactors. The high-voltage DC contactors are installed separately inside the charging pile cabinet, and the production, installation and wiring are more complicated. At the same time, in terms of after-sales maintenance, it is not eas...
